The Bomb Bag is the case in which Link carries his supply of Bombs. In Ocarina of Time it is said that the Bomb Bag is made from the stomach lining of a Dodongo.[1] It is often possible in Zelda games to acquire larger Bomb Bags as Link progresses.

Not all games that include bombs mention a special bag for them. In A Link to the Past for example, a Great Fairy can increase Link's bomb carrying capacity, but the game never specifies how.

Bomb Bag Locations

The following list is arranged by the location of upgrades. The upgrades can be obtained in any order, unless otherwise specified, but the upgrade level's order is unrelated to it. Therefore, the first upgrade collected (regardless of which one) will always be the medium-sized Bomb Bag, while the last upgrade will be the largest Bomb Bag.

Obtainable by going to the Bomb Shop in West Clock Town for only 50 Rupees. They will have the Bomb Bag in stock, and Link can carry Bombchu and Bombs in it. Surprisingly enough, buying this bag is completely optional. See below for more details.

There are two ways to obtain it: It can be obtained by rescuing the Old Lady from Bomb Shop from Sakon's arrest during the night of the First Day; afterwards, the Bomb Shop in Clock Town will have the Big Bomb Bag in stock. Alternatively, he can purchase this bigger Bomb Bag in the Curiosity Shop on the third day if it is already stolen on the first day (it'll be sold at a higher price in this case, however). If the second method is chosen, Link can skip getting the smaller Bomb Bag altogether.

Link can get the final upgrade from the Business Scrub in the Goron Village at Snowhead by trading in his Big Bomb Bag and 200 Rupees.[3] Without the Big Bomb Bag, the bigger product will cost 1000 Rupees and, because the maximum currency cap is 500 Rupees with the Adult Wallet, getting the Biggest Bomb Bag at its original price is impossible.

Locations in Twilight Princess

Bomb Bags work a bit differently in Twilight Princess than they do in other games. The differences are based on that there are multiple Bomb Bags, and only one upgrade:

A Bomb Bag, already packed with bombs, can first be obtained from Barnes in Kakariko Village as part of a special package once he restocks his shop. There are three types of bombs which can be put into it — regular Bombs, Water Bombs, and Bomblings — and the maximum number depends on the type of bomb, being 30, 15, and 10 of each type respectively. Furthermore, only one type of bomb can be used in a bag at a time. To cope with this handicap, two more Bomb Bags can be obtained, as detailed below.

One of the extra Bags is gained by using Bomb Arrows to clear away rubble downriver of Iza's boat rental.

The other Bag is given to the young hero by using Water Bombs to destroy the Molten Shard used to thaw out the throne room of Zora's Domain. The Goron that was trapped inside will reward Link for this.

For the special Bomb Bag upgrade, if Link scores 25 or more points on Iza's river rapid ride game, she will give him the bomb upgrade, which doubles the carrying capacity of all his bags, allowing them to hold up to 60 regular Bombs, 30 Water Bombs, or 20 Bomblings.

Additionally, it's also allowed to store the same type of bomb in more than one bag. This way, Link can have a total of either 90 regular bombs, 45 water bombs or 30 Bombling at first; with the Big Bomb Bag, numbers are doubled to 180 (regular), 90 (water), and 60 (Bomblings). In Twilight Princess, therefore, Link can carry the highest number of regular bombs in any Zelda adventure to date.
